SHIELD has its own television series, but it's yet to have its own film in the Marvel Cinematic Universe. It still has a significant part to play in the Marvel Cinematic Universe, though. The Strategic Homeland Intervention, Enforcement and Logistics Division played a major role in "The Avengers," and it seems like fans can expect them to be an even bigger part of "Captain America: The Winter Soldier."

The upcoming present-day set Captain America adventure features Scarlett Johansson's Black Widow, Samuel L. Jackson's Nick Fury and Cobie Smulders' Maria Hill as major players. Zap2it spoke with Smulders following Marvel's San Diego Comic-Con panel about the role SHIELD has to play in "The Winter Soldier."

"SHIELD has a very strong presence in this film, and it's very cool to see it like that," she says. "This movie takes place after the Battle of New York, and SHIELD is trying to figure out how to control the public and how to like make sure people are safe but everyone is aware that these aliens exist and what does that mean and do people feel safe? We sort of pick up there, but I can't really say anything. Cap is very heavily involved in SHIELD, and the relationship between him and SHIELD is very strong."

Spoilers for "Marvel's Agents of SHIELD": Smulders also has a fairly big role in the "Marvel's Agents of SHIELD" pilot, which was screened at Comic-Con. When asked whether she'll be back again in Season 1, she seemed genuinely uncertain.

"You know, I don't know," she says. "I was asked very kindly by Joss the Wonderful -- that's how I actually refer to him is Joss the Wonderful, he demands that I call him that. He is a wonderful man and his brother Jed [Whedon] and Maurissa [Tancharoen], they were very kind to ask me to come in and do the pilot, and I was really excited because I love Clark Gregg, and I was basically able to be his Vanna White and be like, 'See? He is alive.' I didn't do it like that. I did it a little better than that."

Smulders continues, "It was really exciting to do. Anything Joss wants me to do I do because he's amazing. I don't know how the rest of the series is going to go. They have an amazing cast and they don't need another cast member. They're kind of doing an amazing job and I'm just excited to see how the series unfolds." End spoilers.

Smulders also talked about the "How I Met Your Mother" Comic-Con panel, which had fans camping out overnight for the cast's first -- and likely last -- appearance in San Diego for the show. As Zap2it already reported, the response to the "How I Met Your Mother" panel was overwhelming, and Smulders seemed humbled by it.

"It was pretty amazing, right?" she says. "We like live in this like little bubble and when they were like, 'Fans are camping out!' I was like, 'For us? We're just a sitcom. We just like to have fun and laugh with each other.'"

"Captain America: The Winter Soldier" is due in theaters on April 4, 2014.
